STOP AND WASTE COCK.

T 0 all whom it may concern:

Be it known that I, THOMAS B. HENsEY, a citizen of the United States,residing at Adrian, in the county of Lenawee, State of Michigan, haveinvented certain new and useful Improvements in Stop and Waste Cocks;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to combined stop and waste cocks, and has for oneof its objects to simplify and improve the construction and increase theefficiency and utility of devices of this character.

Another object of the invention is to provide a simply constructeddevice of this character which may be operated in either direction, sothat no matter in which way the plug may be turned the waste duct willbe arranged in operative position.

With these and other objects in view the invention consists generally ina casing having a water passage extending therethrough, and with a wastepassage extending in longitudinal alinement with the water passage andspaced therefrom, and with valve seats communicating through the waterpassage and the waste passage, with the waste passage communicating withthe water passage at one side of the seats, and a plug engaging theseats and provided with transverse passages at right angles to eachother, one passage adapted to register with the water passage when theplug is arranged in one position, and the other passage of the plugadapted to register with the waste passage when the plug is arranged inanother position.

The invention further consists in certain novel features of constructionas hereafter shown and described and then specifically pointed out inthe claim, and in the drawings illustrative of the preferred embodimentof the invention, Figure 1 is a side elevation of the improved device.Fig. 2 is a longitudinal section of the same.

The improved device comprises a casing 10 of the usual form and providedwith a water passage 11 extending therethrough, and with valve seats 12communicating through the passage. Formed in the casing 10 is a wastepassage 13, the waste passage spaced from the water passage 11 andextending in parallel relations thereto. The

Specification of Letters Patent.

Serial No. 477,500.

waste passage opens through the side of the casing at one end as shownat 14 and communicates with the passage 11 at the other end as shown at15, the latter being located at the discharge end of the casing, whilethe open terminal 14 is located at the intake end of the casing.

Mounted for rotation in the seats 12 is a plug 16 having the usualbinding nut 17 and the wrench head 18. Formed through the plug 16 is theusual main passage 19 adapted to register with the passage 11, when theplug is arranged in one position and to out OK the flow when arranged inanother position, in the ordinary manner. Formed through the plug 16 atright angles to the passage 19 is a waste passage 20, the latter adaptedto register with the waste passage 13 when the plug 16 is arranged inone position, or with the passage 19 transversely of the casing, asshown in Fig. 2.

The plug 16 may be rotated in either direction to cause the passage 11to be opened or closed, and by the arrangement of the waste passage 20at right angles to the water passage 19, the waste passage will belikewise opened no matter in which direction the plug may be turned.

In an ordinary arrangement of combined waste and stop cooks, the wastepassage is rendered operative only when the plug is turned in onedirection, and as valves of the class to which the improved deviceherein described appertains are frequently located at inaccessiblepoints, it is a matter of great inconvenience for the operator to knowin which direction to turn the plug, to cause the opening of the wastepassage. \Vith the improved device, however, the waste passage isrendered operative no matter in which di rection the plug may berotated. This is a matter of great convenience, and materially increasesthe utility and efiiciency of the device without materially increasingthe expense of the construction.

The improved device may be applied to valves of various sizes, and tovalves employed for various purposes and constructed from variousmaterials.

that is claimed, is

A combined stop and waste cock compris ing a casing having a transversevalve seat and a main longitudinal water passage extending through thevalve seat, said casing having a waste passage communicating with thevalve seat at one side and with a waste 10 passage of the casing whenthe waste passage of the plug is disposed in registering positionwith'the oppositely disposed waste passages of the casing. V

In testimony whereof, I afiix my signature, in presence of twowitnesses.
